Dynamic chart dataproviders

Question

It's very easy to definie charts in mxml, but in actionscript
I am wondering how I could define a dynamic, unbounded
arraycollection to be the dataprovider for a chart. For example, in
mxml you might have the code from below, but what if you don't know
at runtime, how many series you will have in your chart?
I could do something like this in a for loop:
genericChart.dataProvider = myData; // myData is a generic
ArrayCollection
// for loop start
var seriesList:ArrayCollection=new ArrayCollection();
var columnSeries:ColumnSeries = new ColumnSeries();
columnSeries.xField="point1"; // problem
columnSeries.yField="point2"; // problem
seriesList.addItem(columnSeries);
// for loop end, then assign series to chart
genericChart.series = seriesList.toArray();
but labeling the xField and yField are a problem since I
don't know the names of them in a dynamically created
Arraycollection. Any idea on how to make this work?
